Can you tell us about these districts? Are they GOP strongholds. Why are they open? ect.
The TN district voted for McCain over Obama by over 2:1, but was more competitive in the 2000 presidential election and was traditionally a Democrat district. DJ, why did the Dem resign?
The OK district has a 2:1 Dem registration edge but the district has been voting heavily GOP for awhile. The incumbent Democrat resigned when he accepted a federal appointment.
The seat in OK was held by a Democrat maybe forever since that area used to be heavily Dem. This is far from a GOP stronghold in OK. Except for President and Congress, they have always leaned very much Dem in this area.
